In 1992，Teen Talk Barbie was released with the controversial voice fragment， "Math class is hard." While the toy's release met with strong public reaction，this underlying assumption persists，spreading the myth that women do not thrive in science，technology，engineering and mathematic （STEM） fields due to biological inadequacies in math aptitude.However，in 2019 Jessica Cantlon at Carnegie Mellon University led a research team that comprehensively examined the brain development of young boys and girls and found no gender difference in brain function or math ability.
Cantlon and her team conducted the first neuroimaging study to evaluate biological gender differences in math aptitude of young children.Her team used functional MRI（核磁共振）to measure the brain activity in 104 young children （3-to-10-year-old；55 girls） while watching an educational video covering early math topics，like counting and addition.The researchers compared scans from the boys and girls to evaluate brain similarity.In addition，the team examined brain maturity by comparing the children's scans to those taken from a group of adults （63 adults；25 women） who watched the same math videos.
After numerous statistical comparisons，Cantlon and her team found no difference in the brain development of girls and boys.In addition，the researchers found no difference in how boys and girls processed math skills and were equally engaged while watching the educational videos.Finally，boys' and girls' brain maturity were statistically equivalent when compared to either men or women in the adult group.
Cantlon said she thinks society and culture are likely steering girls and young women away from math and STEM fields，as previous studies show that families spend more time with young boys in play that involves spatial cognition（空間認(rèn)知）. "Typical socialization can make worse small differences between boys and girls that can snowball into how we treat them in science and math，" Cantlon said. "We need to be aware of these origins to ensure we aren't the ones causing the gender inequities."
However，this project is focused on early childhood development using a limited set of math tasks.Cantlon wants to continue this work using a broader scope of math skills，such as spatial processing and memory，and follow the children over many years.

A．It has raised a storm of applause.
B．Girls perform no worse than boys in math.

A．Parents should lengthen the time spent with girls.
B．Society is causing a greater gender difference in math abilities.
C．Culture plays a leading role in children's brain development.
D．We should cultivate boys' and girls' math abilities equally.
（3）How will Cantlon further her research？ AA
A．By using a wider range of math skills.
B．By involving a broader scope of subjects.
C．By increasing the complexity of math tasks.
D．By following the children until their adulthood.

2．Each year on Halloween，children look forward to trick-or-treating （不請(qǐng)客就搗亂） for candies．But for some kids，eating Halloween candies can be dangerous．
That's because one out of every 13 kids in the Us have a food allergy（過(guò)敏癥）．They are allergic to ingredients（成分）in many Halloween candies，such as peanuts，tree nuts，milk，eggs，and beans．If they eat these foods，they will get sick or even die．
"I had to throw away all my candies with tears，" eight-year-old Conlen said．Conlen is allergic to peanuts，tree nuts，and dairy．Twelve-year-old Kylie is allergic to peanuts and tree nuts．She has been trick-or-treating only twice． "I brought my candies home and gave them to the neighbors，" Kylie said． "It felt terrible．"
But this year，Conlen，Kylie and other kids with food allergies will have a chance for a happy Halloween．That's because nearly 100，000 households across the US have promised to take part in the Teal Pumpkin Project（TPP），which was started last year by Food Allergy Research & Education（FARE）．FARE is an organization that works to improve the lives of people with food allergies．Through the project，the households agree to have nonfood items for trick-or-treaters，including trinkets（小飾品） and toys．
To take part in the project，people buy a teal（藍(lán)綠色） pumpkin or paint a pumpkin teal and place it in front of their house．The painted pumpkins let trick-or-treaters know that nonfood items are available there．The households also add their home addresses to an online map，making it easier for trick-or-treaters to find them．
Kylie loves the idea．"The TPP makes Halloween fun and safe，" she said．"It makes me feel like a normal kid，and it makes everyone feel included．"
（1）To Conlen and Kylie，the past Halloween were．
A．upsetting and dangerous
B．interesting and special
C．sick and terrible
D．important and exciting
（2）According to the passage，we know that FARE．
A．helps people with food allergies recover
B．helps the households take part in the TPP
C．takes action to change kids' bad eating habits
D．helps kids with food allergies have a happy Halloween
（3）The households help kids with food allergies by．
A．giving them teal pumpkins as gifts
B．offering them all kinds of food except candies
C．providing them with trinkets and toys as treats
D．a(chǎn)sking them for home addresses and sending them gifts
（4）Where is the passage most probably taken from？
A．A magazine about the history of festivals．
B．A news report on cultures and customs．
C．An advertisement for an organization．
D．A research paper on kid's health．發(fā)布：2024/12/19 20:30:1組卷：36引用：3難度：0.7 -
3．Besides the excitement of travel，one reason to study abroad is that you will experience new customs，holidays，foods，art，music，and politics first-hand.
"I learned the language and am now fluent，but perhaps what's more important is how much I learned about cultures，people，and myself.I learned this from the viewpoint of an active member of the community and my host family，not from the tourist's point of view，" says Andrew，who studied in Poitiers，F(xiàn)rance.
Another reason for studying abroad is that you'll gain self-confidence.Christina studied in Caracas，Venezuela，a city of more than 3 million people and a huge change from her hometown of 35，000!Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language.What could make you more confident than that？
Living away from home can also help you adjust in the transition（過(guò)渡）to college and adulthood.Mathew says he returned from studying in Australia with confidence and a real interest in international affairs that made him different from his peers（同齡人）. "After having gone abroad in high school，I found the transition to college a breeze—moving 560 miles from home didn't seem particularly frightening after having lived thousands of miles away."
Most of all，it's fun while you're studying in a different learning environment.
（1）What is the passage mainly about？
A．Learning a language.
B．The excitement of travel.
C．Living in a foreign country.
D．The benefits of studying abroad.
（2）What did Andrew pay special attention to while studying abroad？
A．Host families.
B．The foreign cultures.
C．Places of interest.
D．Community problems.
（3）According to the example of Christina，what do we know about studying abroad？
A．It can change our habits.
B．It can offer us opportunities.
C．It can increase our knowledge.
D．It can build our confidence.
（4）What do the underlined words "a breeze" in paragraph 4 probably refer to？
A．Something very important.
B．Something very interesting.
C．Something very easy.
D．Something very soft.發(fā)布：2024/12/19 17:0:2組卷：5引用：2難度：0.5
